School of Science and Technology, Online Counseling Resource… What We Learn………….  Replication initiates at ‘oriC’ where consensus sequences are present.  The DnaA protein recognizes the 13bp repeats & starts denaturing DNA.  Pre-priming complex establishes which carry out initiation with the help of proteins SSB & DNA gyrase.  Leading strand & lagging strand elongation carry out by DNA pol III core subunits at origin by extending the RNA primers formed by Primase.  β-sliding clamp of DNA pol III recycles to elongate lagging strand from one okazaki fragment to other.  ‘Ter-Tus’ complex helps in termination of replication.  Catenanes are formed which separated & then located in daughter cells.
